B. MPLS

C. DWDM

D. FCIP

What is a benefit of PowerPath/VE with RSA encryption relative to array-based data encryption?

A. Data encrypted before transmission to the array

B. Reduces CPU overhead on the host

C. Reduces SAN bandwidth requirements

D. Eliminates the need for key management

Average SAN Bandwidth: 3 Gb/s

-

Average LAN Bandwidth: 2 Gb/s

What is the minimum number of dual-port CNAs you would need to install in the server to meet bandwidth requirements while providing CNA redundancy?

B. 2

C. 3

D. 4

You are using virtual (thin) provisioning to reduce the amount of physical storage that is initially required for an implementation.

On the storage array, you configure a pool that contains 20 TB of physical storage and then define several LUNs that total 100 TB. These LUNs are presented to several hypervisor clusters. Virtual Machines are subsequently created using a thick format for the virtual hard disks.

What is the maximum capacity that can be allocated for VM hard disks in this configuration?

A. 20 TB

B. 100 TB

C. 120 TB

D. 2000 TB

An organization seeks to solve a business problem by licensing software from a supplier. The supplier contract stipulates that the software will only be supported if it runs on server platforms also provided by that supplier.

What is this an example of?

A. A virtual appliance

B. A legacy application

C. Enterprise Application Integration

D. Vendor lock-in

You are deploying a virtualized application in a high-availability configuration with automated VM restart on a hypervisor cluster. Your sizing estimates show that peak workloads will saturate the processing power of four hypervisor servers. To meet the SLA, N+2 redundancy is required on the hypervisor servers, with server utilization not to exceed 80% under any conditions.

What is the minimum number of nodes that you should configure in the hypervisor cluster?

A. 5

B. 6

C. 7

D. 8
